Andrew Kyle Purtell resolved HBASE-26537.
-----------------------------------------
Hadoop Flags: Reviewed
Release Note: HBASE-15676 introduced a backwards incompatible change which
makes it impossible to upgrade server first, then client, without potentially
incorrect scanning results if FuzzyRowFilter is in use. This change corrects
that problem by introducing a backwards compatible workaround.
Resolution: Fixed

> HBASE-15676 introduced a backwards incompatible change which makes it
> impossible to upgrade in our designated upgraded order (server first, then
> client) without potential bad results. Worse, the failure mode is silent – a
> pre-HBASE-15676 client would incorrectly receive 0 results from a
> post-HBASE-15676 server.
> I solved this internally as part of our upgrade from 1.2.0 to 2.4.6 by adding
> a new proto field to switch between the two implementations. I'm submitting
> this Jira to capture and potentially backport that fix for anyone else who
> encounters it.
